Gluten-free lemon meringue bars recipe using just 6 ingredients? Get out of here! Well, actually stick around because this is a bake you definitely don’t want to miss. Of course, it’s Coeliac-friendly and wheat-free too.
Gluten-free lemon meringue bars recipe – a buttery shortbread base topped with a sweet and sharp lemon filling, topped with a sweet, marshmallow-y soft Italian meringue. What’s not to love?
As much as I love creating fun bakes like Celia the gluten-free Caterpillar, sometimes you’ve got to pull out a little showstopper… and my gluten-free lemon meringue bars most definitely call into that category!
But just because you’re getting a little more ‘Bake Off’ in the kitchen, that doesn’t mean things have to get complicated or stressful.
(I can’t imagine the pressure that comes with baking knowing Paul Hollywood is constantly judging you!)
With just 6 simple ingredients, you can whip these up and everyone who’s lucky enough to get a slice will immediately crown you a star baker. Yet nobody would ever know they’re gluten-free!
Why make my gluten-free lemon meringue bars recipe?
- They don’t taste gluten-free AT ALL – muggles will eat these, so make sure you save a slice for yourself.
- You only need 6 ingredients and yes, one of those are lemons!
- You’ll learn how to make the super fluffy, light and sticky Italian meringue, which is a great little skill to have in your back pocket.
- Believe it or not, you can easily make this recipe dairy-free by making one simple swap.
- One bite of that buttery base, zesty lemon filling and fluffy, sweet meringue is worth every second you spend making these – promise!
So what do my gluten-free lemon meringue bars taste like?
The base is a buttery, slightly crumbly (but never falling to pieces in your hand!) shortbread that almost soaks up all that wonderful zesty flavour.
The lemon filling is basically a set lemon curd – sweet, sharp and incredibly more-ish. Then it’s topped with marshmallow-y, whippy, Italian meringue – my favourite type of meringue by far!

Gluten-free lemon meringue bars recipe: What you’ll need…
- Gluten-free plain flour – I use Doves Farm’s FREEE flour, which you easily find down the free from aisle in supermarkets. If you can’t find a blend like this where you live, you can always make your own using my gluten-free flour recipe.
- Xanthan gum – This helps to bind the base together so it doesn’t become crumbly, replacing the gluten that would otherwise do the same job.
- Caster sugar – Of course, sugar isn’t just for sweetness – it helps to achieve form a stable consistency and golden finish in the lemon filling. It’s also essential for creating meringue!
- Butter – Ensure yours is softened before you start. You can always use Stork hard margarine if you’re dairy-free too.
- Lemons – You’ll need the zest and juice, meaning no extracts or flavouring required.
- Large eggs – I used large eggs for this recipe, so in the nature of keeping things as similar as possible, I’d recommend that you do too!
- Cream of tartar – This is optional, but if you have it, I’d always recommend adding it. It helps to stabilise your egg white mixture.
So I thought I’d kick things off with a little frequently asked questions section – if you just want the recipe, then keep scrolling.
But I’ve thrown in some tips here that will be really helpful if this is your first time making this, or you want to adapt it. So here they are!
Gluten-free lemon meringue bars recipe: Frequently Asked Questions
Is this recipe gluten-free?
It is gluten-free, though nobody would know just by tasting it – trust me!
Bear in mind that minimising cross-contamination is hugely important if you’re Coeliac or making this for someone who is. Here’s some tips from Coeliac UK on minimising the risk of cross contamination.
Also, make sure that all ingredients used don’t have any gluten-containing ingredients. Then make sure that they also don’t have a ‘may contain’ warning for gluten, wheat, rye, barley, oats (which aren’t gf), spelt and khorasan wheat (aka Kamut).
Here’s some more info from Coeliac UK on identifying safe gluten-free products.
Can I make your gluten-free lemon meringue bars recipe dairy free?
Yep and all you have to do is use a block of Stork hard margarine instead of butter. That’s it!
Can I make your gluten-free lemon meringue bars recipe vegan?
Unfortunately not as this recipe relies a lot on eggs for the fillings and for the meringue too. By the time I adapted this to be vegan, it would basically be an entirely different recipe!
But if you do want an egg-free version, please let me know. If enough people ask, I’ll happily make it.
Are your gluten-free lemon meringue bars recipe low FODMAP?
Yup, this recipe completely low FODMAP and totally safe for the elimination phase of the diet.
Are the eggs cooked in an Italian meringue? I’m worried about raw egg!
Yes, they are completely cooked! The reason we have to be particular about how hot the sugar syrup mixture gets is because it needs to be hot enough to cook the egg whites.
Once it reaches the optimum temperature and you mix it into your whipped egg whites, it’ll cook them without you even knowing. That’s why Italian meringue is hot when it’s finished whisking!
Can I use a food processor or stand mixer to make this?
You can happily use either a food processor, stand mixer or an electric hand whisk to make the shortbread base.
For me, because there isn’t any prolonged mixing periods, I find an electric hand whisk to be more than sufficient for the job!
Can I make your gluten-free lemon meringue bars recipe completely by hand?
Yes, though making meringue by hand can take a while due to the extended whisking periods required. But it is more than do-able, you’ll just need a little extra elbow grease.
Do I need any special equipment to make your gluten-free lemon meringue bars recipe?
As I mentioned, you should definitely make this recipe by hand, so you certainly don’t need any crazy appliances or anything like that.
What you will need however is a 9″ square baking tin – here’s the one I use. Apart from that, you’ll just need a little baking paper too!
Can I use gluten-free self-raising flour instead of plain?
I wouldn’t recommend it – gluten-free plain flour is the way to go for this recipe.
Why? Well, we don’t want the shortbread base to rise at all! It needs to be flat in order to be the perfect base for your caramel.
Otherwise you won’t get those distinctive layers and it can make the shortbread very fragile.
Can I make this recipe using other gluten free flours like buckwheat flour or coconut flour?
There’s a big difference between ‘gluten free plain/self-raising flour’ and a *singular* type gluten free flour.
When I say ‘gluten free plain or self-raising flour’ in a recipe, I mean a BLEND of gluten free flours, not just one, singular flour. I buy mine down the free from aisle of my local supermarket.
Definitely go for a gluten free flour blend.
Do I need weighing scales to make your gluten-free lemon meringue bars?
In short… yes, yes and yes! And I wouldn’t advise attempting any my recipes without them.
A lot of work went into fine tuning ratios and quantities and for me, baking is all about consistency and precision. I want you to make this recipe and for it to turn out EXACTLY like mine did.
I’d recommending using digital cooking scales like these so you know you’re getting an accurate measurement and replicating my recipe as accurately as poss.
How can I tell when my gluten-free lemon meringue bars are done?
You’re looking for slightly golden edges, which are a sure sign that they’re done. Of course, don’t over do it or the lovely golden top will start to brown – they’ll still taste the same, but they won’t look quite as nice!
How long can I keep my gluten-free lemon meringue bars for?
I’ve kept them for about 4-5 days in an air-tight container in the fridge with no problems.
Can I freeze my gluten-free lemon meringue bars?
I wouldn’t recommend freezing these as the meringue is lovely and soft (not like a hard, crunchy meringue) so it can defrost rather unpredictably.
